1. High-precision design and manufacturing process
Huazhi Mould uses advanced CAD/CAM software to accurately design automobile grille mold parts. By simulating and analyzing the molding process, optimizing the design details, and controlling the dimensional accuracy within ±0.05mm, it is ensured that the mold parts can perfectly replicate the design intent during the production process. For example, in the manufacturing of a luxury car grille mold part, our design team designed a unique grille shape mold part through in-depth research on aerodynamics and aesthetics, which not only improved the appearance of the vehicle, but also optimized the air intake efficiency.
In the manufacturing process, the company is equipped with high-precision five-axis linkage machining centers, slow-wire wire cutting machines and other equipment. These devices have nano-level positioning accuracy and high-rigidity structure, and can perform fine processing on mold parts with complex shapes. Whether it is fine texture carving or sharp corner processing, it can be accurately presented to create a delicate appearance for the air intake grille.

2. High-quality materials guarantee excellent performance
Knowing the key role of materials in the quality and service life of mold parts, Huazhi Mold only uses high-quality steel from internationally renowned suppliers. For example, P20, 718 and other steels commonly used for automobile air intake grille mold parts have good cutting performance, polishing performance, and high strength and toughness. After a special heat treatment process, the surface hardness of the mold parts can reach HRC30-HRC40, which effectively resists wear and deformation during the injection molding process and ensures long-term stable production operation.

3. Efficient cooling and thermal balance system design
Automobile air intake grille mold parts require precise temperature control during the injection molding process. Huazhi Mold carefully designs the cooling water channel layout and adopts special cooling medium circulation technology to enable mold parts to dissipate heat quickly and evenly during the injection molding process. This not only shortens the molding cycle and improves production efficiency, but also effectively avoids defects such as product deformation and shrinkage caused by local overheating. For example, in the production of a certain mass-produced model’s air intake grille mold parts, our cooling system shortened the molding cycle by 20%, and at the same time increased the product qualification rate to more than 98%.

4. Advanced surface treatment process
In order to meet the stringent requirements of the automotive air intake grille for appearance quality, Huazhi Mould provides a variety of advanced surface treatment processes. The polishing process can make the surface of the mold parts achieve a mirror effect, with a roughness Ra value as low as 0.2μm, giving the air intake grille a smooth and bright appearance. Nitriding treatment can form a nitride layer with high hardness, good wear resistance and certain corrosion resistance on the surface of the mold parts, further extending the service life of the mold parts and ensuring stable performance and appearance quality during long-term use.

5. Strict quality control system
Huazhi Mould has established a complete quality management system, and strictly controls every link from raw material inspection to finished product delivery. Advanced three-coordinate measuring instruments, projectors and other testing equipment are used to conduct comprehensive inspections on the dimensional accuracy and form and position tolerances of mold parts. During the production process, a multi-process inspection system is implemented to timely discover and correct processing errors to ensure that every automobile grille mold part meets high quality standards. The company has passed the ISO 9001:2015 quality management system certification, which provides reliable guarantee for product quality.
